Abstract

The invention relates to the steering of a bucket wheel excavator (6) for producing planned surfaces in open-cast mining, in particular in quarrying and open-cast lignite mining, by a continuous measurement of the area exposed by the bucket wheel and controlled follow-up of the bucket wheel into the required position for producing the predetermined surface, the bucket wheel being steered by a pulsed laser beam produced in a rotary laser (8, 9) carried along by the machine. <IMAGE>
